How did you define your customized editor to the system? In other words
where did you tell it to use your editor. The exact XMI is needed.

Thanks for your reply!

I use override method to define my customized editor.

In plugin.xml, add this extention:

<extension
point=3D"org.eclipse.jem.beaninfo.registrations">
<registration
container=3D"org.eclipse.customize.example.container">
<override
package=3D"org.eclipse.customize.example"
path=3D"overrides/org/eclipse/customize/example">
</override>
</registration> =20
</extension>

And an override file under folder =
"overrides/org/eclipse/customize/example":

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<xmi:XMI xmi:version=3D"2.0" xmlns:xmi=3D"http://www.omg.org/XMI"
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance"
=
xmlns:org.eclipse.ve.internal.cde.decorators=3D"http:///org/eclipse/ve/in=
ternal/cde/decorators.ecore"
xmlns:ecore=3D"http://www.eclipse.org/emf/2002/Ecore"
xmlns:event=3D"event.xmi">
<event:Add featureName=3D"eStructuralFeatures">
<addedEObjects xsi:type=3D"ecore:EReference" name=3D"text" =
unsettable=3D"true">
<eAnnotations
=
xsi:type=3D" org.eclipse.ve.internal.cde.decorators:BasePropertyDecorator "=

=
cellEditorClassname=3D"org.eclipse.customize.example/org.eclipse.customiz=
e.example.CustomLabelEditor" />
</addedEObjects>
</event:Add>
</xmi:XMI>

And the name "text" is the name of a property I declared in my beaninfo =
class.

Are there anything wrong? It seems that the BundleLoader know my editor =
name(org.eclipse.customize.example.CustomLabelEditor) but can't find my =
editor class.

Best regards,

Hexise

I debug this plugin in runtime environment, not export it to a plugin jar
file.
And the .class file do exists in the bin folder of my project, I don't know
why the BundleLoader can't find it? Did I miss something?
Thanks again for your reply!

But is it in the project that is your development plugin
org.eclipse.customize.example? It needs to be in a plugin, whether
plugin is a jar or is the development project that you are using to
development the plugin (i.e. the projqct that contains the MANFIEST.mf
that defines your org.eclipse.customize.example plugin).

I find the answer to this problem...
The first half of the cellEditorClassname definition in override file is =
the plugin id, I missunderstood it to be the package name...So lead to =
this exception.

How did you define your customized editor to the system? In other words
where did you tell it to use your editor. The exact XMI is needed.

Thanks for your reply!

I use override method to define my customized editor.

In plugin.xml, add this extention:

<extension
point=3D"org.eclipse.jem.beaninfo.registrations">
<registration
container=3D"org.eclipse.customize.example.container">
<override
package=3D"org.eclipse.customize.example"
path=3D"overrides/org/eclipse/customize/example">
</override>
</registration> =20
</extension>

And an override file under folder =
"overrides/org/eclipse/customize/example":

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<xmi:XMI xmi:version=3D"2.0" xmlns:xmi=3D"http://www.omg.org/XMI"
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance"
=
xmlns:org.eclipse.ve.internal.cde.decorators=3D"http:///org/eclipse/ve/in=
ternal/cde/decorators.ecore"
xmlns:ecore=3D"http://www.eclipse.org/emf/2002/Ecore"
xmlns:event=3D"event.xmi">
<event:Add featureName=3D"eStructuralFeatures">
<addedEObjects xsi:type=3D"ecore:EReference" name=3D"text" =
unsettable=3D"true">
<eAnnotations
=
xsi:type=3D" org.eclipse.ve.internal.cde.decorators:BasePropertyDecorator "=

=
cellEditorClassname=3D"org.eclipse.customize.example/org.eclipse.customiz=
e.example.CustomLabelEditor" />
</addedEObjects>
</event:Add>
</xmi:XMI>

And the name "text" is the name of a property I declared in my beaninfo =
class.

Are there anything wrong? It seems that the BundleLoader know my editor =
name(org.eclipse.customize.example.CustomLabelEditor) but can't find my =
editor class.

Best regards,

Hexise

I debug this plugin in runtime environment, not export it to a plugin jar
file.
And the .class file do exists in the bin folder of my project, I don't know
why the BundleLoader can't find it? Did I miss something?
Thanks again for your reply!

plugin is a jar or is the development project that you are using to
development the plugin (i.e. the projqct that contains the MANFIEST.mf
that defines your org.eclipse.customize.example plugin).

I have verified that the .class file exists in the bin folder of =
org.eclipse.customize.example plugin project, but why the BundleLoader =
can't find it?
Another phenomenon is that, I have an Activator class extends from =
AbstractUIPlugin, I set it to be the activator of this plugin, but it =
has never been accessed during my debugging. I think there should be =
some problems.

Thanks.

Best Regards,
Hexise

I find the answer to this problem...
The first half of the cellEditorClassname definition in override file is =
the plugin id, I missunderstood it to be the package name...So lead to =
this exception.
Thanks for your help, Rich! Thanks for your time!
